Earlier today I started feeling crummy and several hours later I’m still feeling crummy. Checking the air pressure reading on Environment Canada’s website, I can see that I started feeling crummy shortly after the air pressure started falling. In fact, in the last six hours, the pressure has dropped almost 0.5 kPa.

This isn’t surprising given there’s a low pressure zone that’s passing to the south, as you can see in the snippet from the most recent surface analysis. (Ottawa is the red dot and Lake Huron is just north of the L.)

Hopefully, the pressure changes will settle down because feeling out of sorts and not being able to do anything about it sucks.
